Exercise 31 Page 599

Substitute the value of x into the second equation.

E

Practice makes perfect

We are given two equations and asked to evaluate the value of y. x=6/4p+3 xy=3/4p+3To do this, we can substitute the value of x into the second equation and simplify.

xy=3/4p+3

Substitute

x= 6/4p+3

6/4p+3* y=3/4p+3

MoveRightFacToNum

a/c* b = a* b/c

6y/4p+3=3/4p+3

Next, we will multiply both sides of the equation by (4p+3) to eliminate the denominator of both fractions.

6y/4p+3=3/4p+3

MultEqn

LHS * (4p+3)=RHS* (4p+3)

(4p+3)*6y/4p+3=(4p+3)*3/4p+3
